Design and synthesis of 3,7-diarylimidazopyridines as inhibitors of the VEGF-receptor KDR
摘要:
3,7-Diaryl substituted imidazopyridines were designed and developed as a new class of KDR kinase inhibitors. A variety of imidazopyridines were synthesized and potent inhibitors of KDR kinase activity were identified with good aqueous solubility. (C) 2004 Elsevier Ltd. All rights reserved.
Computer aided drug discovery of highly ligand efficient, low molecular weight imidazopyridine analogs as FLT3 inhibitors
摘要:
The FLT3 kinase represents an attractive target to effectively treat AML. Unfortunately, no FLT3 targeted therapeutic is currently approved. In line with our continued interests in treating kinase related disease for anti-FLT3 mutant activity, we utilized pioneering synthetic methodology in combination with computer aided drug discovery and identified low molecular weight, highly ligand efficient, FLT3 kinase inhibitors. Compounds were analyzed for biochemical inhibition, their ability to selectively inhibit cell proliferation, for FLT3 mutant activity, and preliminary aqueous solubility. Validated hits were discovered that can serve as starting platforms for lead candidates. (C) 2015 Elsevier Masson SAS. All rights reserved.
The first Pd-catalyzed tandem cyclization of imidazo[1,2-a]pyridines with 2-chlorobenzaldehydes throughC–Harylation and acylation is presented for the efficient synthesis of novel 6H-benzo[b]imidazo[5,1,2-de]quinolizin-6-ones. The direct acylation reaction proceeded smoothly without the aid of directing groups and in the presence of air as a clean and free terminal oxidant.

The present invention relates to imidazopyridine compounds which inhibit, regulate and/or modulate tyrosine kinase signal transduction, compositions which contain these compounds, and methods of using them to treat tyrosine kinase-dependent diseases and conditions, such as angiogenesis, cancer, tumor growth, atherosclerosis, age related macular degeneration, diabetic retinopathy, inflammatory diseases, and the like in mammals.
